Configuring Access and Trunk Interfaces

Configuring Access Host Ports

Configuring Access Host Ports

By using switchport host, you can make an access port a spanning-tree edge port, and enable bpdu filtering and bpdu guard at the same time.

Before You Begin

Ensure that you are configuring the correct interface; it must be an interface that is connnected to an end station.

Procedure

	Command or Action	Purpose
Step 1	switch# configure terminal	Enters configuration mode.
Step 2	switch(config)# interface type	Specifies an interface to configure, and enters interface
	slot/port	configuration mode.
Step 3	switch(config-if)# switchport host	Sets the interface to spanning-tree port type edge, turns
		on bpdu filtering and bpdu guard.
		Note	Apply this command only to switchports which
			connect to hosts.

This example shows how to set an interface as an Ethernet access host port with EtherChannel disabled:

switch# configure terminal switch(config)# interface ethernet 1/10 switch(config-if)# switchport host

Configuring Trunk Ports

You can configure an Ethernet port as a trunk port; a trunk port transmits untagged packets for the native VLAN plus encapsulated, tagged, packets for multiple VLANs.

Note Cisco NX-OS supports only 802.1Q encapsulation.

To configure a trunk port, perform this task:

Procedure

	Command or Action	Purpose
Step 1	switch# configure terminal	Enters configuration mode.
Step 2	switch(config)# interface {type	Specifies an interface to configure, and enters interface
	slot/port port-channelnumber}	configuration mode.
